Problems solved by technology

[0002] At present, the clamping mechanism of injection molding machine and die-casting molding machine mainly uses sliding fit between the movable platen and the frame when moving the mold, and uses pull rods to slide and fit guide supports. Multiple sliding fit guide supports will produce various unstable frictional resistances. The speed of the mold moving process is unstable, the frictional resistance is large, and the acceleration of the mold moving is slow, resulting in a long mold moving cycle and low machine production efficiency. The moving template and the frame are supported by linear guide rails, which is a more advanced technology at present.
